  1. Hi I use Z77. I use ASRock Z77 Extermr4 board and BCM57781 LAN (Onboard). It was ok until High Sierra. But after install High Sierra, The onboard LAN keeps disappearing. It does not seem to have LAN at all. On linux, lspci, on windows, device manager and on mac lspci/ioregistryexplorer.... There's no lan. The only way to get it back is the CMOS reset. (Not a bios lload default menu, H/W jumper clear). I wonder if others have this problem.
  2. Hi all, new the community and just installed 10.9. I'm running into some trouble getting the ethernet up and running. I've tried a bunch of kexts but none of them seem to work. Not sure if I don't have the right one or I'm doing something wrong. Also, I'm not sure how to get my GTX 660 working. It is recognized in the system profile, graphicsenabler=No but when I switch to in the bios, I get hung up on the loading screen. If anyone has any suggestions please let me know.. Thanks!!
  3. I wasn't able to enable network support on installation; I installed the BCM57781 kext for my onboard Asrock x79 extreme6 and now when I go into network preferences it just hangs on the spinning colour wheel. Is there other kexts I should remove? Any input would be much appreciated.. Thanks
  4. hi, I have a ASRock Z77E-ITX mainboard and last week updated to 10.8.3 without any issues (combo update). I only have to install the IONetworkingFamily.kext (which i also used in 10.8.2) and audio kext, but i have some strange behavior with downloading files and for example youtube movies. I can easily reproduce the error to do some speedtest @www.speedtest.netand do a test, the test wil abort after a while. also download a speedtest file of 1GB it says network connection broken. On some youtube movies i see that some movies are not fully downloaded and abrupt sometimes. i have tried to reinstall the kext (first deleted), but also same issue. i also cannot find a newer version of this kext: "IONetworkingFamily.kext BCM57781" i use (BuildVersion - 602). someone any idea? tips?
